PROBLEM TO BE SOLVED: To obtain a conductive conjugate fiber that has sufficient conductive performance, has slight reduction in conductive performance and strength even after moist heat treatment such as sterilization, etc., and is suitably useful for clothing such as operation uniform for clean room, medical application, interior use such as curtain, etc., and industrial uses. SOLUTION: The conductive conjugate fiber comprises a nonconductive component composed of a polyester-based resin and a conductive component composed of a polyester-based resin containing a conductive particle and exhibits a shape in which at least a part of the conductive component is exposed to the surface of the fiber. Specific amounts of an antimony compound and a phosphorus compound are contained in the conductive conjugate fiber. The conductive conjugate fiber of moist heat resistance has 1×10<SP>6</SP>Ω-1×10<SP>9</SP>Ω/cm electrical resistivity,≤20 electroconductivity reduction ratio after moist heat treatment (treatment at 121°C for 25 hours) and≥75% strength retention after moist heat treatment (treatment at 121°C for 25 hours).
